JOHN F. McAVOY, OF BALTIMORE, MARYLAND.

UMBRELLA AND PARASOL.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed March 21, 1906. Serial No. 307,140.

To all whom, it natty concern:

Be it known that I, Jonn F. MoAvoY, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Umbrellas and Parasols, of which thefollowing is a specification.

This invention relates to improvements in umbrellas or parasols, and hasparticular reference to those devices employed to pivotally secure theribs and stretcher-bars in position about the rod.

One object of the invention is to provide detachable and independentretaining devices for the ribs or stretchers whereby to enable a brokenor damaged rib to be readily removed and a new one substituted.

Another object of the invention is to provide a construction whereby theretaining parts are interchangeable and which may be formed from sheetmetal, thus reducing the cost to a minimum.

With these and other objects in view the invention is illustrated in theaccompanying drawings, in which Figure 1 illustrates a portion of anumbrella or parasol rod which ls 'provided with the improved retainingdevices, which latter are shown partly in section. Fig. 2 is an enlargedsectional detail of the retaining devices. Fig. 3 illustrates anenlarged perspective view of the spacing-ring employed on the runner,and Fig. 4 is a perspective view of one of the detachable rib-retainers.

Referring to the drawings by numerals, 1 designates the umbrella orparasol rod, which may be of any desired form and on one end of which issecured a metal. sleeve 2. This sleeve has position on that end of therod which is opposite to the handle and which in the present case willbe termed the lower end. The upper .end of this sleeve is provided withexterior screw-threads 3 for a purpose to be presently described. A ringor collar 4 surrounds the lower flared end 5 of the sleeve and is heldrigidly in place by means of a in 6, which extends through said ring ands eeve and also through the rod.

The function of this ring is tosustain and space the rib-retainingdevices. This ring has a circular portion 7, which snugly fits thesleeve, and its wall above said circular portion extends outwardly at 8,so as to form an annular space 9 around the sleeve. The upper end of thering is provided with a lateral flange 10, which has a plurality ofvertical projections 11 at regular intervals apart, forming horizontalseats 12 between each two projections.

The rib-retaining devices are independent of each other, and eachcomprises a plate 13, which. is curved to conform to the circumferenceof the sleeve, and projecting laterally from said plate are parallelears or lugs 14, each of which has a perforation 15, through which a pinor rivet 16 passes. The position of the ears or lugs is such that theplate proj ects both above and below the latter, so that the lowerportion of the plate may fit down or enter the annular space 9 betweenthe sleeve and ring, while the lugs 14 will project over the flange 10of the ring and lie on the seat 12 between the projections 11., and thusbe held from lateral movement.

The ribs 17 may be of any preferred form; but each has its lower endsfitted between the lugs 14 of one of the plates 13, so as to bepivotally connected to the lugs by the pins or rivets 16. Thestretcher-bars 18 are also pivoted at one end to the ribs as usual, andtheir other ends are pivoted to the lugs or plates the same as the ribs,so that each rib and stretcher-bar is pivotally connected bc tween thelugs of a rib-retainer.

In order to hold the plates 13 against the sleeve 2, a retaining-collar19 is placed over the sleeve and embraces all of the said plates, and aninternally-threaded locking-collar 20 is then screwed down on thethreaded end of the sleeve and crowds the retaining-collar down over theends of said rib-retaining plates and holds the latter rigidly in place.

At the upper or handle end the rod 1 is provided with a tubular runner21, having the usual slot 22 for the reception of the usualretaining-spring. The lower end of this runner is provided withscrew-threads 23, and between said screw-threads and said slot therunner is provided with an exterior shoulder or circumferential head 24.A spacing ring or collar 25, similar to the collar 4 on the lower sleeve2, surrounds the runner and has position just beneath the bead 24:. Thiscollar is also provided with vertical projections and horizontal seatsor recesses between each two projections for the lugs of thestretcher-bar-retaining devices to fit into. A retaining-collar 26 isalso employed to sur round the runner and to hold thestretcherbar-retaining devices against said runner, while alocking-collar 27 screws onto the lower end of said runner and holds theretaining-collar in place.

The operation of the runner on the rod will raise or lower thestretcher-bars and ribs in the usual manner, while the construction ofthe rib and stretcher-bar-retaining devices is such that by looseningthe collars any particular rib and stretcherbar that has be come damagedmay be quickly removed and a new one substituted by an unskilled person.

The construction of the various parts is such that they may all bestamped from sheet metal and the cost of IIHLIIU'fELGUlI'G thereforeminimized.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. An umbrella or parasol having a rod; a stationary sleeve near one endof said rod; ribs pivotally sustained about said sleeve; a runner havinga screw-threaded end; a ring surrounding said runner and having anannular space between it and the runner; a retaming-collar alsosurrounding said runner and having an annular space between it and saidrunner; a plurality of removable plates seated. in said annular spacesand clamped between said ring and collar and surrounding I the runner; ascrew-threaded collar engaging the threads on the runner for clampingthe plates between the ring and retainingcollar; a stretcher-barpivotally connected to each of said plates, and means for pivotallyconnecting the stretcherb ars and ribs.

2. An umbrella or parasol having a rod, a stationary sleeve near one endof the rod; a ring surrounding the sleeve and having a lateral flangewhich is provided with a plurality of vertical projections; independentretain ing-plates surrounding the sleeve and each plate having lugswhich project between two vertical projections of the ring-flange; a ribpivotally connected to the lugs of each of said plates; a runner also onthe rod and stretcher-bars pivotally connected to the ribs and runner.

3. An umbrella or parasol having a rod, a stationary sleeve near one endof said rod; ribs pivotally sustained. about said sleeve; a runner; aring surrounding said. runner and having a lateral flange which isprovided with a plurality of spaced-apart vertical projections; aretaining-collar also around the runner; a plurality of removable platescurved to conform to the circumference of the runner and havinglaterally-projecting lugs, said plates being held at their upper andlower edges by the ring and collar; stretcherbars pivotally connected tothe lugs of the removable plates and also to the ribs.

In testimony whereof I aHiX my signature in presence of two witnesses.
